trans cooler confusion

[poissonverte]

Im lost here.. trying to install a hayden trans cooler. The helms is confusing me too. Theres two outlets on the transmission. Which one is going out which one is going in?? I guess the better question is what is the flow with the radiator included in the equation. One line runs along the radiator and plugs into a metal block where the another line is connected and the other runs into a T section which connects to the left side of the trans cooler (facing outwards), and the other line coming from that metal block.. IIMMM soo confused, probably just reading into it to mcuh though. dont have a host to post pics, but can email them.. headbang headbang

the lines run from the tranny into the top of the radiator (i think) then out of the bottom of the radiator, into the metal cooler that is in front of the A/C & radiator, then back into the tranny.

Heat rises so the fluid is dumped at the top, and exits near the bottom where the coldest coolant is, hence why the waterpump draws from down low.

I think i figured it out.. PLEASE correct me if im wrong. Fluid leaves transmission and goes to the little silver block. Some fluid continues into the lower radiator inlet while the other fluid goes back along the same route to the T-section and back into the trans. The fluid enters the lower radiator port travels up and out the top. Near the top of the radiator runs a tube into the passenger side of the trans cooler. Out the drivers side cooler it connects to the T-section and into the transmission..

That small metal "box" is a thermostat for the tranny fluid. The tranny fluid flows as follows. Out of the tranny and into the "box" if it is too cold it comes back out the box and through the tube that goes to the "T" fitting and then back into the tranny. If the fluid is hot enough the thermostat or "box" lets it go through it, then into the radiator, then out the radiator and into the tranny cooler (if already equipped) if not it goes from the radiator back to the tranny. That is how it is routed on my 95, I did not like having that thermostat their so I took out the "T" fitting and replaced it with a straigh fitting, and removed the thermostat and made that a free flowing passage. So at all times my tranny fluid is flowing through the radiator and the cooler. That thermostat has also been known to become stuck as not to allow the fluid to flow even if it is hot enough. So, I removed mine. Hope this long post clears everything up for you.

Thanks shotimer.. Helped alot.. Ijust edited my post when you posted.. heh.. beer beer cheers

Glad you figured it out, took me a few minutes of exploration to figure out the flow of that stuff.
What kind of cooler are you installing? I'm looking to upgrade my stock one.

Hayden model 1403.. 25 bucks from bulkpart.com Question is where to put it. They suggest attaching it to the other cooler and leave a small space with rubber feet between the two.

Im probably going to zip tie it 3 times to the front plastic face down at the bottom. Still have room to run up a curve and scrap the skirt, and not damage it.. Unless someone finds this a bad idea.. I found out if i lose line pressure the atx runs like total crap, so if that happens I know I can pull over quickly etc..

 

[poissonverte]

Before I beat this thing to a bloody pulp.. How does one disconnect those silver thimbels connecting the trans tubes together at different locations?? Hate to trash one.

 

[SHOtimer]

I bet it wasn't a pleasant experience finding out that the ATX doesn't run well without line pressure.

When I did mine they simply unscrewed out of each other...righty tighty, lefty loosy. It took some muscle to loosen they become rather comfy in their spots.

Thanks.. yeah on the lemans one of the lines was degraded so bad it split 5 inches worth.. The car jerks constantly.. Kinda like a person just learning to drive stick.. Had to fix it in the parking lot of the local ********** after it made it there, but couldnt get home the next morning ) boink

I have a question about this since I came up empty handed on a search.

Since these lines have a t-stat (stated above), if it (SHO) hasn't been running for a while and then started and it starts to leak at the line connections, could this be from that t-stat not opening and builing up pressure and leaking out? If not, is there a way some pessure can be build up to make it leak at the connections right up on the trans? This car never had any tranny leaks, just coolant leaks when it hasn't been running for a while and then started up. Both leaks seem simular and both have t-stats. I don't know what to think shrug , but any help is appreciated.

 

[SHOtimer]

Your leaky tranny lines could be due to just loose fittings, or worn out rubber lines. The tranny t-stat has a return line so when it is closed the fluid is just rerouted back to the tranny, unless their is a blockage their is no pressure build up.
